Create Jenkins pipeline job parameters from yaml

README.md

Jenkins Pipeline Parameters Party

Not that you would, but if you DID add a whole bunch of parameters for your pipeline job... why not have it in version control?

To avoid the obligatory 500 million unsafe script approvals readMyProps may need to got to workflow-libs folder

Jenkinsfile.groovy

def myText = '''
properties:
  - param: booleanParam
    args:
      name: ENABLE_AAT
      defaultValue: true
      description: "Should we run AATs"
  - param: stringParam
    args:
      name: NEXT_BUILD
      defaultValue: '${env.BUILD_NUMBER.toInteger() + 1}'
      description: 'Choose the next build number'      
'''

node('master') {
    stage('yaml') {
        def myYaml = readYaml text: myText
        def myProps = readMyProps myYaml.properties
        
        properties([
            parameters(myProps)
        ])
    }
}

def readMyProps(properties) {
    
    properties.collect { parameter ->
      this.invokeMethod parameter.param, parameter.args.collectEntries { name, value ->
        [
          name, 
          value instanceof String ? interp(value) : value
        ]
      }
    }
}

  new groovy.text.GStringTemplateEngine()
    .createTemplate(value)
    .make([env:env])
    .toString()
}
